To all 'whom-t mag/'concern' a citizen' ofxthe United: States,jand `a resident "of Honolulu,wTerr itory of-Ha'waiu Honolulu, H.,) have inventedcertain new and useful Improvementsqin-` Attachments for Centrifugal' Machines; and .l do

\ hereby "declare: the following. to be i a' .full,

clear, and exact description of. the invention, l suchr as will enablelothersskilled inthe arti., to which it appertains to make and use vthe vsame.- .u This invention relates to improvementsgin centrifugal machines, by means of which the materials of .various specic gravities motion.

molasses in which said crystals were formed, but itV isto be understood that theinvention is not limitedl to ruse in sugar,` `separating machines, as. it fis .conceivable and contemvplatedithat it may. be used in various other connections.

VA. pair of brackets 7 are Vsecured tothe topA of the casing by suitablev means, such asboltsS, and extending betweenthe corresponding ends of these brackets is a bolt 9,

l on. which a bridge member 10 is pivotally mounted. This bridge member is provided with `'a u pair of A horizontally extending arms 70 "11, lwhich are Aarranged to swing between the brackets 7. On the opposite ends of the brackets `7, clips 12 are mounted on bolts 13, the latter servin also to secure the brackets to the casing. hese clips are arranged to swing over the arms 11 'so as to prevent the upwardmovement of the arms and the consequent swinging. movement of the bridge member 10. These clips are maintained in their operative positions by wingednuts :14,wliich are adjustably mounted on 'the bolts 13. lVlien these nuts are loosened, A however, the clips will be permitted to swing out ofthe path tof movement of the arms 1'1,

and consequently permit the movement ot. 85

the bridge `memlber.y l p.

A 'Journal 15V extends vbetween the arms 11y 'and isheld stationary bya tap-bolt 16,

'on which journal a gathering -and discharging, element '17 1sA mounted for swinging 90 movement. This element 17 includes a channel memberl 18, which extends downwardly and toward the peripheral wall of the basket and also curves inra direction substantially .concentric with the basket and in a direction opposite to that of the rotation of the basket.l The 'end of this channel member `isprovided with an opening'or mouth 19 :into which the material to be gathered is forced-"during the movement of the basket. A channeliextends upwardly Jrom this mbuth119 and opens at 21 into the annular spacefi between'the wall of the basketiand theadjacent vvvallof the casing 3, so-that the material passing through the channel willbe discharged into the glitter 5 and will subsequently pass from the orifice 6.

The passage of the glutinous or waste material through the channel 20 is greatly enhanced because of the presence of the ejector 22, which projects into the channel 20 in alinement with the opening 21. This ejector is provided with supply means 28, by which steam is supplied to the ejector. The passage of the steam through the channel 20 not only dilutes the glutinousmaterial so that it will flow more easily, but also forces the material from the opening 21.

In order that the mouth 19 may be swung so as to be located a greater or lesser distance from the imperforate wall of the bracket 2, I have extended from the element 17 a pair of arms 24 in which elongated openings or slots 25 are formed. Trunnions 26, extending from the ends of a yoke-member 27, are located within these openings, as clearly illustrated in Figs; 2 and 4 of the drawing. A veitical spindle 28 extends through and has screw-threaded engagement with the yoke 27 and is mounted in suitable bearings carried by the bridge member 10. The/upper end of this spindle is provided with a hand-Wheel 29, so that the spindle may be rotated and during the rotation will either raise or lower the yoke 27, and consequently swing the element 17 about its pivot and cause the mouth 19 to move with relation to the wall of the revolving basket.

It will be clear from the above description that when the winged-nuts 14 are loosened and the clips 12 are swung out of the path of movement of the arms 11, the entire device may be swung about the bolt 9 as a pivot into such a position as illustrated in dotted lines in Fig. 1, where the element 17 will be withdrawn from the separating basket. Furthermore, upon the adjustment of the hand-Wheel 29, the mouth 19 of the journal 20 may be swung to collect material from the baskct irrespective of the distance of the material from the wall of the basket.

In operation, when the revolving basket is set in motion, the materials to be separated will, of course, arrange themselves in the order of their specific gravities, the material of the greatest specific gravity being adja-. cent to the wall of the basket 2, and wherc sugar crystals are being separated from the remaining noncrystallized material, the latter material will be the innermost layer of material. After the basket has revolved for a sufficient length of time to permit the materials to properly arrange themselves, the element 17 is swung into the basket so that the mouth 19 of the channel 20 will project into the material which is to be gathered and discharged. As the separating basket revolves at a comparatively high rate of speed, the material is forced into the mouth 1. In a centrifugal machine for separatinoi sugar crystals from noncrystallized materia a revolving imperforate basket, means for gathering the material and conveying the same from the basket, and means for diluting the material and for forcibly discharging the same.

2. In a centrifugal machine, a revolving basket for arranging the materials according to their specific gravities, means for separating the material of one specific gravity from the remaining materials and for con veying it from the basket, and means for accelerating the passage of said material from said basket.

3. In a centrifugal machine, a revolving basket for arranging the materials according to their specific gravities, means for separating the material of one specific gravity from the remaining materials and for conveying it from the basket, and a steam jet discharging into said means.

4. In a centrifugal machine, the combination with a basket, ofA a pivoted channel member extending into the basket and having the mouth ofthe channel opening in the direction opposite to that in which the basket revolves, and means for adjusting the member about its pivot to vary the distance between the mouth of the channel and the Yperipheral Wall of the basket.

V. In a centrifugal machine, the combination with a basket, of a pivoted 'channel member extending into the basket and having the mouth of the channel opening in the direction opposite to that in which the basket revolves, means for adjusting the member about its pivot to vary the distance between the mouth of the channel and the peripheral wall of the basket, and means for diluting the material as it passes through the channel and for forcing the material from the channel.

6. In a centrifugal machine, the combination With a casing, of a basket revolubly mounted therein, a bridge member pivotally mounted on the casing, a channel member pivotally mounted on the bridge member and extending into the basket, said channel member being constructed and arranged to collect material from the basket, and means for pivotally adjusting said member.

7 In a centrifugal machine, the combination with a casing, of a basket revolubly mounted therein, a bridgemember mounted on the casing on ahorizontal pivot, means 5 for securing the bridge member against piv otal movement, a channel member pivotally mounted on the bridge member and extending into the basket, and an adjusting screw carried by the bridge member and engaging the channel Vmember for moving the latter 10 about its pivot.

In testimony whereof I afix my signature.
